Abstract

HAY PROVISTO UN PROCESO PARA OBTENER UN BISFENOL A DE ALTA PUREZA PARA ELIMINAR LA MAYOR PARTE DE FENOL DE UN ADUCTO DE BISFENOL A CON FENOL Y ELIMINAR CONTINUAMENTE EL FENOL RESIDUAL POR EXTRACCION DE VAPOR, EN DONDE UNA COLUMNA EMPAQUETADA MULTITUBULAR ES USADA EN UN ACCESORIO DE EXTRACCION. DE ACUERDO CON EL PROCESO DE LA PRESENTE INVENCION EL FENOL RESIDUAL EN BISFENOL A PUEDE SER ELIMINADO CONSTANTEMENTE. EN ADICION, EL PROCESO DE LA PRESENTE INVENCION ES ECONOMICO PORQUE EL FENOL RESIDUAL PUEDE SER ELIMINADO CON UNA PEQUEÑA CANTIDAD DE VAPOR.A PROCESS HAS BEEN PROVIDED TO OBTAIN A HIGH PURITY BISPHENOL A TO ELIMINATE THE MAJORITY OF PHENOL FROM A BISPHENOL A ADDICT WITH PHENOL AND CONTINUOUSLY ELIMINATE THE RESIDUAL PHENOL BY USED MULTIPLE GASKET PACKAGE EXTRACTION. IN ACCORDANCE WITH THE PROCESS OF THE PRESENT INVENTION THE RESIDUAL PHENOL IN BISPHENOL A CAN BE CONSTANTLY REMOVED. IN ADDITION, THE PROCESS OF THE PRESENT INVENTION IS ECONOMIC BECAUSE THE RESIDUAL PHENOL CAN BE ELIMINATED WITH A SMALL AMOUNT OF STEAM.
